A CORPORATION OF RHOIJE ELASTIC-BRACELET LINK.

Specification of Letters Patent.

Patented Apr. 7, 191 1.

To all whom it may concern Be it known that I, JOHN H. HnNNnssEY, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented anew and useful Improvement in Elastic-Bracelet Links, of which the following is a specification.

This invention pertains to certain new and useful improvements in bracelets, and relates more particularly to bracelets of the expansion type in which the several links are normally held in contracted relation by coil springs.

The objects of the invention are to provide novel, improved and simplified means for uniting the several links to allow of increased expansion of the bracelet as a whole, and to otherwise generally improve the structure and component parts thereof.

In the drawings-Figure 1 is a side elevation of a bracelet constructed in accordance with the present invention. Fig. 2 is a detail fragmentary View in top plan. the top of the unit being removed. Fig. 3 is a vertical sectional view of one of the links showing the parts in contracted position. Fig. 4 is a view similar to Fig. 3, but showing the parts in expanded position. Fig. 5 is a detail perspective view of one of the links of the coupling means, and Fig. 6 is a view similar to Fig. 5 of another of the parts of the coupling means.

Each unit is composed of a top member 1,

l and a bottom member 2 each being of hollow form. The bottom member 2 has a pin 3 secured to one end and a tube 1 secured to its other end, while the top member 1 has a pin 5, secured to one of its ends, which pin engages in the tube 4 of the bottom member, and a tube G-secured to its opposite end, which tube 6 receives the pin 3 of the bottom member 1. The top and bottom members are spaced apart and sliding in said spaces are the links 7. The inner ends of the links slidingly receive the tubes 4 and 6 at the adjacent ends of the units, and said inner ends have the studs 8 rigidly connected thereto. Coil springs 9 have one end secured to the studs 8 and their opposite 1 ends secured to the pins 5 and 3. When the parts are in contracted position, the inner ends of the links 7 abut, being drawn into such relationship due to the action of the pins 12 of the couplings so as to slide in relation thereto, permitting the links to have an oscillatory movement with respect to the pins 12.

From the above it will be seen that the two coil springs 9 of each unit are secured at their opposite ends to the top and bottom members of said unit, and that the free ends of the said springs are connected to the inner ends of the links 7. Thus the springs 9 exert tension on the links in opposite directions which permits the links to move to the extreme ends of the units, thereby providing greater expansion of the parts than otherwise.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A bracelet link comprising aunit of hollow form, a pair of slotted links having their inner ends disposed in the interior of the unit, projections secured to and arranged on the interior of the unit which projections extend through the slots of the links to guide the same in their sliding movements, pins carried by the inner ends of the links, and coil springs connected to said projections farthest from the pins and to the latter.

2. A bracelet link comprising a unit of hollow form, a pair of substantially alined links for the unit having their inner ends arranged in the interiorof the unit, a pin carried by the inner end of each link, the pins of the pair of links extending in opposite directions from each other, a spring pin, and a spring connected to the otherv 5 pin and extending over the first named link and connected to the other end of the unit.

In testimony whereof I have Signed my name to this specification in the presence of two subscribing Witnesses.

JOHN H. HENNESSEY.
